Sound waves undergo reflection and refraction, much as electromagnetic waves do. Here is one practical application of reflection and refraction in the field of health care: determining the location of a liver tumor. Suppose that a narrow beam of ultrasonic waves travels through surrounding tissue and enters the liver with an incidence angle of 51.0°. These inaudible sound waves travel 14.5% more slowly through the liver than through the medium that lies above. Suppose that the beam reflects off the tumor and emerges from the liver at a distance 11.0 cm from its entry point. Calculate the depth of the tumor (in cm) below the surface of the liver. 11.0 cm 51.0° i Liver Tumor 2.85 Once the beam enters the liver, its path to the tumor can be thought of as the hypotenuse of a right triangle.

One leg of that triangle is known: it is half the separation between the incident and emerging beams at the liver surface. The other leg is the quantity you seek: the depth of the tumor. Be sure to keep track of the difference between index of refraction and sound speed (they are inversely proportional to one another). cm
